Prescription eye glasses are essential for some people to be able to see clearly. They allow some to be able to drive and for others to be able to simply see anything. Prescription glasses are made special for each individual after an eye exam by an eye doctor. After it is determined what lenses you need to be able to see clearly, you can pick frames to your taste. It takes a few days to have them made and sent back to the place you had your exam done and the order was made. After the glasses arrive they are fitted and they ensure that you can see out of them before leaving. More info: prescription glasses Calgary
